This product seemed to work very well on an 18 year old Toyota truck which had a previous owner who neglected maintenance. I flushed with this product and then did a "rinse flush" with distilled water two times thereafter. System is clean!

It really did help with my cooling system being full of rust. In the directions it says to put new coolant in right after the flush, but I had to put new purified water in the engine. Run it until fans came on. Drain it. Put water in radiator fill with bottom plugs off until clear. I repeated this three times until the water was clear.
Worked for ME!

Worked extremely well. Highly recommend, but be sure to know how to flush your radiator and how much time it's gonna take.
My Saturn SL2 was pretty bad and in need of a good cleaning, and this stuff sure worked. Thanks GUNK
